      <p style="margin-left: 40px;">Jpcap is a Java
class package that allows Java applications to capture and/or send
packets to the network.</p>

      <p style="margin-left: 40px;">Jpcap
is based on <a style="color: rgb(255, 102, 102);" target="_blank" href="http://www.tcpdump.org/">libpcap</a>/<a style="color: rgb(255, 102, 102);" target="_blank" href="http://www.winpcap.org/">winpcap</a>
and Raw Socket API. Therefore, Jpcap is supposed to work on any OS on
which&nbsp;<a style="color: rgb(255, 102, 102);" target="_blank" href="http://www.tcpdump.org/">libpcap</a>/<a style="color: rgb(255, 102, 102);" target="_blank" href="http://www.winpcap.org/">winpcap</a>
has been implemented.&nbsp;Currently, Jpcap has been tested on
FreeBSD 3.x, Linux RedHat 6.1, Fedora Core 4, Solaris, and Microsoft
Windows 2000/XP.</p>

      <div style="margin-left: 40px;">Jpcap
supports the following types
of packets: Ethernet, IPv4, IPv6, ARP/RARP, TCP, UDP, and ICMPv4.
&nbsp;Other types of packets are captured as raw packets (i.e.,
instances of the Packet class) which contains the whole data of the
packets. &nbsp;This allows Java applications to analyze unsupported
packet types.<br>
